Hi! I drive a Spacetourer RipCurl Edition BJ 2018. From a speed of approx. 65kmh on the driver’s side a whistle/wind noise becomes audible in the area of the side mirror which becomes louder and louder to me and which is very disturbing by the Pfeifton auxh. On the passenger side nothing is perceptible, although the side mirrors are identically large. If someone already knows the problem or what could be the exact problem, since it occurs only on the driver side. Thank you. Mfg Flo
